The test section is octagonal ,of 2.5 m wide, 2.0 m high and 4 m long. The tunnel is powered by a 1200 kW, air cooled variable speed DC motor which drives a 12 blade, 3.5 m diameter fan and is equipped with a six component pyramidal type external mechanical balance with a 700 Kgf maximum lift capacity.The angle of attack range is between -45o and +45o while the yaw angle range is between -140o and +216o .The data acquisition system has been modified recently to allow the recording of all test data on a PC - type computer using LABVIEW and a PXI ¨C type chassis containing specialized data acquisition modules.The tunnel is equipped with a variable frequency electrical supply system for powered models and a 10 bar compressed air supply for pneumatic flow control applications.In the recent years the subsonic wind tunnel has been intensively used for tests within several European projects (AVERT, CESAR and others). %U http://bulletin.incas.ro/files/florin_munteabu_v1no1_2_full.pdf
